MOLD-CARRIAGE.

To all whomit may concern Be it known that I, HARRY I-I. DE Loss, acitizen of the United States, residing at Bridgeport, county ofFairfield, State of Connecticut, have invented an Improvement inMold-Carriages, of which the following is a specification.

This invention has for its object to provide a carriage especiallyadapted for casting purposes, which will carry molds into position toreceive molten metal from the pouring spout of a stationary furnace orfrom a tilting furnace and which shall be so constructed as to permitthe molds to be reciprocated during the pouring operation, therebydispensing with the labor and inconvenience of drawing or pouring themolten metal into a crucible and reciproeating the crucible during theoperation of pouring into the molds.

With these ends in View my invention consists in certain novelconstructions, combinations and adjustments which will be here inafterdescribed and then specifically p0inted out in the claims hereuntoappended.

In the accompanying drawing forming a part of this specification, Figurel is an end elevation of my novel carriage as seen from the left inFigs. 3 and 4:, parts being in section; Fig. 2 is a similar view showinga changed position of the parts, as in raising or lowering the upperends of the molds; Fig. 3 a side elevation as seen from the rightin Fig.1, and Fig. 4 is a plan View.

So far as I am aware the operation of casting ingots is now performed bydrawing or pouring the molten metal from the furnace into a crucible orother receptacle which must be lifted and held raised and reciprocatedbodily over the top of the mold in order that the pouring may not be inone place in the mold. This is in order to pre vent streaks, spills, airholes and other defects in the ingots, it having been found necessary inorder to secure sound and solid ingots to deliver the stream of moltenmetal from end to end of the opening in the mold by moving the crucibleor other pouring ves- Specification of Letters Patent.

sel backward and forward over the mold.

My present invention enables me to handle two molds at a time, to placethem in convenient position to receive the metal from the furnace, tomove the mold that is being filled backward and forward as the pouringproceeds and when the mold is filled to move the other mold intoposition to be filled and to reciprocate the second mold in the samemanner, all without any lifting whatever.

The invention furthermore does away with intermediate handling of themolten metal and permits delivery of the metal from the furnace directlyinto the molds, thereby reducing the exposure of the molten metal to theatmosphere to the minimum and greatly reducing the loss from oxidationof the metal.

My novel carriage as a whole comprises essentially a lower carriage 10and an upper carriage 11. The lower carriage is of greater width thanlength and consists sin1- ply of a relatively strong frame which may beconstructed in any ordinary or preferred manner and is provided withwheels 12 upon which it is adapted to be moved backward and forward andwith transverse tracks or rails 13. The upper carriage is provided withflanged wheels 14 which are adapted to travel on the tracks, with a base15, with a foot piece 16 and with a hinged support 17 upon which theupper ends of the molds rest, as indicated by dotted lines. This supportis made high enough to provide for varying lengths of molds which areordinarily supported at an incline, as indicated by dotted lines. As aconvenient rest for the bases of the molds I ordinarily use a block orblocks 18 which may be removable and which rest against the footpiece,the tops of the molds resting upon the hinged support. The support isprovided with a hinged locking arm 19 having notches 20 either of whichis adapted to engage a pin 21 which projects from the base of the uppercarriage. The upper ends of the molds are raised or lowered as may berequired in the top of pouring from difierent furnaces by swinging thesupport toward or from the vertical position, compare Figs. 1 and 2.

22 denotes an oscillating bar, one end of which is pivoted to the uppercarriage as at 23, the other end being provided with notches 2 f eitherof which is adapted to engage a pin 25 which projects from anoscillating lever 26, the lower end of which is pivoted to a suitablebracket 27 projecting from the frame of the lower carriage.

The operation is as follows: The lower carriage with the upper carriageand molds thereon is run up to the furnace in position to receive moltenmetal therefrom. The height of the upper end of the molds is adjusted tocorrespond with the furnace spout by means of the hinged support. Ifadjustment of the upper carriage is required to place either mold inreceptive position, for example the right mold as seen in Fig. 3, thisadjustment is effected by disengaging the oscillating bar from the pinon the operating lever and moving the carriage forward or backward onthe tracks, as may be required. The furnace is then tapped and moltenmetal flows directly into the mold. During this pouring operation theupper carriage is oscillated forward and backward by means of theoscillating lever. This is in order that the molten metal may be causedto enter the mold in a stream which is constantly moving from one end tothe other of the opening in the mold, thereby avoiding streaks, spills,so-called, and air holes in the ingot. The difference between casting bythe use of my novel carriage and ordinary casting is that my novelcarriage provides for oscillating the molds in a simple and convenientmanner, whereas in ordinary casting the metal must be drawn ofi into acrucible or other receptacle and the receptacle must be held in a raisedposition by main strength and moved bodily backward and forward over theupper ends of the molds. Having poured the first ingot the flow of metalis stopped, the oscillating bar is disengaged from the pin and the uppercarriage is moved into position to place the second mold in receptiveposition and then the operation of casting an ingot is proceeded with asbefore. Having cast ingots in the molds upon the carriage, the carriagemay be removed from proximity to the furnace and the molds removed topermit the ingots to cool and other molds placed upon the carriage whichis then run into position for another casting operation as before.

Having thus described my invention I claim:

1. A mold carriage comprising a lower carriage, an upper carriageadapted to support a plurality of molds and to be moved transversely onthe lower carriage and means on the upper carriage for adjusting theheight of the upper ends of the molds.

2. A mold carriage comprising a lower carriage, an upper carriageadapted to support a plurality of molds and to be moved transversely onthe lower carriage, the upper carriage being provided with a hingedsupport upon which the upper ends of the molds are adapted to rest, andmeans for adjusting said support to regulate the height of the upperends of the molds.

3. A mold carriage comprising a lower carriage, an upper carriageadapted to sup port a plurality of molds and to be moved transversely onthe lower carriage, the upper carriage being provided with a hingedsupport on which the upper ends of the molds are adapted to rest and thebase of the carriage being provided with a pin, and a locking armpivoted to the support and provided with notches either of which isadapted to engage the pin.

4. A mold carriage comprising a lower carriage, an upper carriageadapted to be moved transversely thereon, an oscillating bar pivoted tothe upper carriage and an oscillating lever pivoted to the lowercarriage with which the oscillating bar is adjustably connected, wherebythe upper carriage may be oscillated during a pouring operation.
